DUMPlNGI-CART.

SPECIFICATION forming part of Letters Patent No. 605,029, dated May 31, 1898. Application filed Tune 6, 1894; Serial No. 513,652. (No model.)

To all whom it mcbyconaern: 1

Be it known that I, JAMES \VILLIAM TAY- LOR, a citizen of the United States, residing at IIerndon,-in the county of Fairfax and State of Virginia, have invented certain new and useful Improvements in Dumping-Carts and Cranked Axles; and I: do hereby declare the following tobe'a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use thesanie.- I

' My inventionh'elates to improvements in dumpin g-carts and cranked axles; and it consists in certain novel features andcombina tions herein after described and claimed.

The objects of the invention are to make a perfectly water-tight body'or receptacle without resort to packingtoprovide the most convenientand efficient means for tilting the body to dump the contents, for opening and closing the lid '01 cover,and for supporting the body on its axis. I

In the drawings, Figure 1 is aside elevation of myimproved cart. Fig.2 is a plan of the same,ya' part being'brokenaway to show the body-tilting mechanism in elevation. Fig.3 is a side elevation showing-the body in posi- Fig. 4 is a view vation and at the other side the body, the tube extending across the body and the crank-arm in section, the aixle-bar and the wheel-spindles being in elevation. Fig. 0 is a detail showing the locking-plate in section.

A is thecart-body, made ofmetal plate in a way well known. The sides of the body are perforated for the insertion of a. tube a of the I character of a boiler-tube. 1 This tube is fitted in the side walls of the body by riveting or upsetting'the end or in any suit-able way.

At the extremities and within thetube l insert thimbles I to serveas boxes or bearings for the'body hanging on the axle. The axle is built up of 'parts consisting of'a bar 2 and crank-arms and spindles3. The straight bar part2 is made of steel rolled or forged in cylindrical form and the crank-arms and spindles of cast-steel. The crankarms are pro:

vided with hubs or enlargements 3, bored te fit closely over the extremities of the bar part 2 to make a long bearing and a strong and rigid connection between the parts. In this way a cranked axle is made cheaper than by methods of forging as heretofore generally;

practiced, and there is eliminated from the defect of cold shut incident to welding the arm and bar together in the forging process.

The most efficient and con'venientway of securin g the arms to the axle-bar now known to me is to'make the ends of the arm slightly tapering and make the sockets in the crankarm of corresponding shape and proportions;

The crank-arms are driven onto the ends of the bar and finally drawn and secured in place by tapering keys, as shown in the drawings By this method of coupling the parts they are about as firmly connected as if the arms were heated and afterward shrunk on thebars, and there follows the advantage of facilityin separation of the parts or removal of the crank-arms in the event that repairs of any'kind may be desired. In the process of building-my cart the body is completed with The axle, carrying the body,

ing the body provides a perfectly tight cart having a body hung to swing on a standing cranked axle without resorting to packed joints between the body and the axle.

To give .a broad, bearing-surfacefor the body and obviate the tendency of the thin side walls'of the body to cut the tube at the joint between them, I have made the upper end. or head of the crank-arm .on the side next the body of the cart circular in form vand have riveted to the outside of the body plates 4 4, having concave flanged bearingsurfaces to fit over the circular part of the crank-arms. By this construction the heavy weight of the loaded cart is brought to bear on a broad surface, and the strain on thethin sides of the body is distributed, so that there will be neither tearing of the sides at the tubeholes nor cutting of the tubes.

The beams for bolting the cranked axle in a standing position are bolted to the frame at one end, and at the other end they are provided with heads or knobs fitting into recesses in the crank-arm castings, as clearly shown in Fig. l.

The means for tilting the contents consists of a windlass 10, mounted on the frame in front of the cart-body, a common cable-chain 11, connected at both ends to the body, and a take-up attachment 12, interposed between the ends of the chain. It is observed that the body is cccentrically hung on the axle, so that without a take-up there would be slack chain in tilting the body to dump the contents. The take-up attachment shown consists of a frame suspended from the axis of the Wind lass, carrying at its free end guide-rollers 12. The chain is looped around the rag-wheel of the windlass, one end leading around one guide-pulley 12 to the front end of the body and the other end leading from the rag-wheel over the top of the other guide-pulley 12 around and to the rear end of the cart-body.

The means for opening and closing and for sustaining the lid in the desired position consists of a lever 5, pivoted to the side of the body, a link 0, connecting the lever and lid, and catches or stops attached to the sides of the body. In the form shown the catches or steps are formed by notching a segmental flange 7 to one side of the body. The lever 5 consists of a spring-bar and is hung so as to press toward the body, and is thus made to automatically enter the notches in segment 17 and hold the lever in whatever position desired. When the lid is closed, the lever and link are under tension, so as to draw and hold the lid firmly to its seat, and thus insure atight joint with the body. The lever and link are so proportioned and the joints between the link, lever, and lid so adjusted that the first part of the movement of the lid in raising it is about of the same speed as that of the lever, while the latter part of "its movement, when the weight of the lid is nearly balanced, is relatively much greater than that of the lever.

In order to avoid the necessity of manually pushing and working the contents of the cartbody from rear to the front to entirely fill the body and for othereonveniences, I hinge that part of the cover to which the 'seat 8 is attached so that it may be turned up and the cart loaded through. the front end to completely fill the same. A hook or catch 9 is arranged to normally secure the seat in place.

The locking-catch for holding the body in position with relation to the frame consists of a bracket 9, having a recess or socket 9 riveted or otherwise seen red to the front of the cart-body, and. a spring-bolt or snap-catch 71, mounted on the frame of the cart. lhis bolt is eonven iently withdrawn to unlock the body for dumping or other purposes by means of a handle or lever c.

Having described my invention, what I claim is 1. In a dumpingwehicle having a body provided with a tube extending from side to side and suspended from an axle the combination of such body, a bearing-piece attached to the body and an. axle having a cooperating bearing-face substantially 5 described.

2. In a d u niping-vehiele having a body suspended from an axle, the combination of such body, a flanged plate attached to the body, and an axle having a collar outside the body upon which the flanged plate rests to support the body as set forth.

8. In a dl mping-vehicle the combination of a body, a swinging lid, a lever pivoted to one side of the body, and extending downwardly to be operated from the ground, and a link connecting theleverand the lid, substantially as described.

a. In a dumping-vehicle the combination of a body, a swinging lid or cover for said body, a lever alongside the body,and stops or catches alongside the body for holding the lever and the lid in desired positions,substantially as described.

5. In a dumping vehiclc the combination of a swinging body a swing-lid, a lever arranged alongside the body connected with the lid, and a notched segment on the side of the body for holding the lever and lid in desired positions, substantially as described.

(3. In a dumping-vehicle the combination of abody, a lever arranged to project downward by the side of the body, a lid connected with the lever and means attached to the side of the body for holding the lid in a closed position under tension, substantially as described.

7. In a dumping-vol]icle,the combination of an eccentrieally-swinging body, a chain extending around the lower side of said body, a Windlass and a take-up, substantially as described.

In testimony whereof I atlix my signature in presence of two witnesses.
